381	6829 d 12 h	jermar	/SPARTAN/trunk/	Make cross-compiler the default compiler on IA-32. For native compilations, use ./build.ia32 native. Small changes elsewhere.
378	6830 d 22 h	jermar	/SPARTAN/trunk/	Redeclare eraly_malloc() with __attribute__ ((malloc)) to improve optimizations. Reorganize #include's in scheduler.c. Buddy system improvements. Make buddy_system_free() explicitly invalidate order of blocks before they are coalesced. Add some assertions.
377	6833 d 14 h	jermar	/SPARTAN/trunk/	Generic buddy allocator. Please review the code before it is deployed.
374	6835 d 12 h	jermar	/SPARTAN/trunk/	Revert previous change in frame_t as it broke IA-64. (Most likely some alignment problem.) Rename heap_init(), malloc() and free(), respectively, to early_heap_init(), early_malloc() and early_free(), respectively. Define new macros malloc() and free(). They are to be replaced by real functions some day.
373	6835 d 14 h	jermar	/SPARTAN/trunk/	Physical memory management work. Add "__attribute__ ((packed))" to frame_t so that it takes up less space. Note that this is essential as there is lot of these structures. Remove busy list from zone_t as it is redundant.
368	6837 d 21 h	jermar	/SPARTAN/trunk/	Physical memory management work. New frame allocator. Some architectures need to have bigger heap.
367	6838 d 12 h	jermar	/SPARTAN/trunk/	Physical memory management work. Implement zone_() and some frame_() functions.
366	6838 d 13 h	jermar	/SPARTAN/trunk/include/	Add zone pointer to frame_t. This will be essential for fast frame_free(). Rename frame_zone_t to zone_t. Declare frame and zone functions to be implemented.
355	6840 d 20 h	jermar	/SPARTAN/trunk/include/mm/	Add 'base' attribute to frame_zone_t structure.
354	6840 d 20 h	jermar	/SPARTAN/trunk/	Physical memory management work. Define structures for frame zones and frames. Add some comments.
265	6855 d 21 h	palkovsky	/SPARTAN/trunk/	Added basic FPU context (not working). Added CPU utilities from ia32
167	6870 d 21 h	jermar	/SPARTAN/trunk/	Switch over to per vm_t page tables. (breaks ia32 userspace) Define dummy memcopy() for amd64 and ppc to satisfy compiler. Get rid of problematic #include <arch/mm/page.h> in mm/page.h. Indentation fixes and small changes here and there.
125	6905 d 13 h	jermar	/SPARTAN/trunk/	Huge indentation fix.
122	6906 d 12 h	jermar	/SPARTAN/trunk/include/mm/	Remove one extra line left over from debugging process.
121	6906 d 12 h	jermar	/SPARTAN/trunk/	Begin MIPS implementation of 4-level page table interface. Add email address to each item in doc/AUTHORS. Correct type names in comments in mm/vm.c. Introduce ptl0 pointer in vm_t.
120	6920 d 11 h	jermar	/SPARTAN/trunk/	Generic 4-level page tables interface & implementation (review & test). Implement more architecture dependant macros on IA-32. Provide fake implementation on IA-64 and MIPS. Convert map_page_to_frame() to use the new interface. Move adjusted map_page_to_frame() from IA-32's arch/mm/page.c to the generic mm/page.c.
119	6921 d 14 h	jermar	/SPARTAN/trunk/	Start with generic 4-level page table interface. Usual cleanup.
116	6940 d 18 h	jermar	/SPARTAN/trunk/	Add map_structure() to automate mapping of memory structures that can span multiple pages and/or cross page boundaries. Change ACPI map_sdt() to use map_structure(). Small changes in MPS code. The extra frame allocation for accessing frame 0 is unnecessary as it is possible to access frame 0 from kernel address space. Zero TSS descriptor in the newly prepared GDT.
109	6947 d 15 h	jermar	/SPARTAN/trunk/	Discard 'copy' parameter of map_page_to_frame(). Introduce 'root' parameter of map_page_to_frame(). If 'root' is zero, page directory address is read from CPU. Otherwise 'root' is used as page directory address. Add missing word to new doxygen-style comments in scheduler.c.
102	6953 d 14 h	jermar	/SPARTAN/trunk/	IA-64 work. Redefine FRAME_SIZE to "(161024)" instead of "24096". Note that the latter definition was wrong because of the lack of "()". Take panic_printf(), cpu_halt() and memsetb() out of fake.s and implement them properly in asm.S. Move ski_init_console() from arch_post_mm_init() to arch_pre_mm_init(). In start.S, write r0 to ar.bspstore. Janitorial fixes. Add count_t type. Replace several occurrences of int and __u32 by count_t or size_t. Shorten several panic strings.
